8 J. II. Emerton — New England Therididoe. 



many species have liorns or humps on the head, but otherwise differ 

 little from the females. The palj)! of the males are large and com- 

 ))lieated. The tarsal liook is present but usually small and smooth. 

 The tube is of various lengths, but tlie supporting appendages are 

 usually small and not so complicated as in Linyphinm. The tibial 

 hook is iisvxally large and of a great vaiiety of s]ia])es. Most of 

 these spiders live under leaves or near the ground. The webs of most 

 are unknown, but some species make a flat ^veb under leaves like 

 Linyphinm. This group connects with Tlieridinai through Ceratinella 

 and Pholcomma, and with LinytJhincB through Tmeticus and Micro- 

 neta. The following are the genera of this sub-family : 



Ceratinella, SpirojHdpus, Lophocarenxim., 



Ceratiiiopsis, Lophonmia., Gonatiitm, 



Grammonota, Cornicularia, Erigone. 



4. Linyphinse. 

 The smaller species of this group, forming the genus 3Iicroneta, 

 resemble closely Tmeticus of the last sub-family, in the shape of tbe 

 body, and size and colors. The palpal organs show their relations to 

 Bathyphantes. In the larger Linyphhue the legs are long and have 

 long and conspicuous spines. The abdomen is thick and flattened 

 above, or high in front and pointed behind. The male palpi are 

 large and complicated. The tibia is usually short but otherwise not 

 much modified. The tarsal hook is large and varies greatly in shape 

 according to the species. The epigynum is large and in many species 

 folded. The w^ebs consist of a flat sheet supported by irregular 

 threads. The following genera belong to this sub-family : 



Linyphia, Ilelophora, Bolyphantes, 



Dijdostyla, Drapetisca, Microneta. 



Stemonypha^ites, Bathyphantes., 



Theridium Waick. 



Steatoda Monge, Preussisclic spinnen. 



The cephalothorax is broad oval, usually with a dark line along 

 the middle. The abdomen is either nearly spherical or else high in 

 the middle and flattened behind. PI. XVII. The usual markings 

 of tlie abdomen are a scalloped or herring-bone stripe in the middle 

 and dark oblique marks at the sides, but in several species tliese are 

 partly or entirely absent and replaced by othei- markings. The legs 

 are usually 1, 4, 2, ;3, but in hmg-legged males are often 1, '1, 4, 3.
